HEATING DEVICE.'

als of reference marked thereon, which form a part of this specification.

This invention relates to heating devices more particularly for household purposes.

Tt frequently happens that one or more of the rooms in a. house are insufiiciently heated. Moreover, it is often the case that a chimney is located in one ofthe walls of such a room up which a large amount of heat escapes.

One of the principal objects of the present invention is to provide means for utilizing a part of this heat which now goes to waste for heating the air in a room.

A further object of the invention is to provide an improved form of radiator.

Another object of the invention is to profide means for varying the amount of ieat transmitted from the chimney gases to the room. l

An additional object is to provide means for minimizing the deposit of soot in the radiator and means for cleaning the radiator when desired.

Other and further important objects of this invention will be apparent from the disclosures in the specification and drawings.

Ou the drawings Figure 1 is a. vertical section through achimney provided with a radiator constructed in accordance with the present invention.

Figure 2 is a section on the line 2 2 of Figure 1.

Figure 3 is a front elevation of the radiator.

A? shown on the drawings:

The chimney flue 10 is surrounded bythe usual brickwork 11. An aperture 12 is formed in this brick-work on the room side of the chimney and around its periphery is arranged an iron frame 18. This frame not only holds the brick-work in place but also provides means for supporting the radiator 14. The outer edge of the frame 13 is formed with an outwardly extending flange 13St having a rearwardly formed portion 13b esprimermi sied February 15, 1923. serial No. 619,110.

thereon affording an insulating-chamber 13..

which prevents undue transmission of heat to the plaster or Vother chimney covering. For this purposeflthe frame extends outwardly to form a bearing surface iiush with the wallof the room.l On the upper portion of this bearing surface is arranged an upwardly turned lip 15 adapted to engage a downwardly extending lip 16 -on the upper edge of the radiator. The lower part of the radiator is clamped to the frame 13 by a screw 17. y Laterally the radiator is held in position by means of ribs 18.

Across the center of the aperture on the chimney side is arranged a plate 19 forming a part of the frame 13. This plate serves as a support for a rod 2O on which a damper 21 is arranged. This rod extends through the radiator 11i andy is provided at its outer end with a detachable handle 22. By turning the damper the flow of hot gases over the surface of the radiator may be varied.

rFhe radiator itself may conveniently consist. of a cast-iron box formed on the front side with a. series of deep vertical corrugations 23 extending into the aperture 12. By

prevents a person from accidentally comy ing in Contact with the highly heated ysurface of the radiator box.

l am aware that numerous detailsof construction and operation may be varied through a wide ranf-re without departing from the principles or this invention, and l therefore do not purpose limiting the patent granted hereon otherwise than` as necessitated by the prior art.

I claim as my invention:

1. A heating device comprising a chimney having an aperture therein leading to a room, a radiator' arranged in said aperture having one wall substantially flush with the front wall of the chimney, a damper in the chimney behind the radiator, said wall heing apertured above and below said damper to allow chimney geeeeto bye-pase eronnd seid damper when the latter is closed.

2. A heating devioe comprising a Chimney having an aperture therein leading to e room, a radiator arrengedin said perture having a front heat transmitting Well, and ze rear Wall adapted to :tet as a portion of the front Well or the chimney, and a demper behind Said rear Wall adapted when closed to force 'the chimney gases to pass infront ofisaid rear Wall, the latter `beingv apertured above and below7 said damper to allow of such passage of seid gases.

3. A heating device Comprising a chimney,l a. demper in the chimney, a 'by-pees around said demper, a metal Wall for seid ley-,pass having deep verticaly eorrngatlons,

and a series of horizontal ribs thereon.

Ll. A heating device comprising a chunney having an aperture therein]` a easing Within -said aperture having top, bottom, side and rear Walls, the rear Well being` epertured .top and bottoni for the passage of Chimney gases, a damper ybehind Said rear Wall and a detachable front Wall having inwardly extending,eorrugations formed therein.

ln testimony whereof I here hereunto enh scribed my name.
